CBS POSTS LOW NUMBERS FOR WINTER GAMES WARM-UP

          CBS earned a "disappointing" 4.9/8 rating for its two-
     hour Olympic preview on Tuesday night, "but the numbers are
     not expected to be indicative of how the network's upcoming
     Games coverage will perform," according to Lisa de Moraes of
     the HOLLYWOOD REPORTER.  "Gateway to Glory" gave CBS one of
     its "lowest numbers to date in the two-hour block and well
     below" its 6.6/11 season average.   But de Moraes adds that
     networks "schedule primetime Olympic walkups despite their
     historically low ratings in order to accommodate overflow
     Olympic advertising" (HOLLYWOOD REPORTER, 2/5).
